Wouldn't it be easier (and faster, more correct finding answer) to ask the source?
In my experience asking questions of companies you either get ignored, get a canned response that may or may not have anything to do with the question, or get some vague marketing speak sort of answer that doesn't really answer anything. Unfortunately I don't even really consider that as a valid way to get an answer anymore. What a sad state of affairs.
It is odd to get more sales this month than the previous 4 months combined, but since they are almost all subs the total isn't worth writing home about.
